摘要
FIELD: electricity.;SUBSTANCE: alternating current supply system per 25 kV for electrified railroads comprises power transmission lines, traction substations including three-phase three-winding traction transformers with load voltage regulation and transformer oil temperature monitoring sensors, condenser units of longitudinal and transversal capacitive compensation, control room with train and power supply dispatchers, selection box of traction loads supply schemes, temperature control sensors for the most heated points in windings of traction transformers, ambient air temperature and atmospheric pressure sensors, ambient air humidity sensors, statistic data acquisition unit; the unit analysing traction loads supply schemes is coupled through communication lines to the power supply dispatcher, temperature control sensors for the most heated points in windings of traction transformers, ambient air temperature and atmospheric pressure sensors, ambient air humidity sensors are coupled through communication lines to statistic data acquisition unit, which in its turn is coupled to temperature recording unit for the most heated points in windings of traction transformers while the latter is coupled to the unit analysing traction loads supply schemes.;EFFECT: improved operational reliability of the system.;2 dwg
